Kurast Undercity

The Kurast Undercity, introduced in Diablo 4's "Vessel of Hatred" expansion, is a multi-level, time-attack dungeon beneath the city of Kurast (Map). Players race against the clock, defeating enemies and completing events across one of three distinct districts to reach unique bosses. Success is rewarded with valuable loot, scaling with your performance.

The difficulty of the Undercity will always be in line with the difficulty you are playing on, i.e Hard, Penitent or Torment 4 so it will be as appropriate during leveling up as it will be at endgame.

Entrance to the Undercity

Unlocking the Undercity

On completion of the Vessel of Hatred campaign, Ormus (Map) will ask you to undertake a few small quests which introduce players to endgame content, including the Undercity.

To gain access to the Kurast Undercity, start by completing the "Reunion" (Map) quest from the Vessel of Hatred Campaign, ensuring you are Level 15 or above. This accomplishment will activate the Priority Quest "The Kurast Undercity," (Map) beginning at the Kurast Bazaar. From there, you will navigate through a series of tasks, moving between different areas of the city and the Undercity itself, tackling challenges in each district. The quest chain ultimately leads to a confrontation with Alia, marking the final step to fully unlock the dungeon and complete the storyline.

Accessing the Undercity

The entrance to the Undercity is different to the one you used in the Campaign Quest (Fundament of Faith Map). It is still in Kurast but it's on the eastern side of town. The dungeon entrance portal will appear once you have activated the Spirit Brazier in the same area.

Tribute and Bargain

Offering a Tribute and Bargain at the Brazier allows you to customize the kinds of rewards you receive for completing the Undercity. You do not need to offer a Tribute to enter the Undercity.

Offering a Tribute & Bargain at the Spirit Brazier

Tributes can be earned by completing activities such as Nightmare Dungeons, events, Whispers and Undercity runs (see table below). They are fairly rare drops. These Tributes can be offered at the Spirit Brazier to target specific rewards for your next run, but doing so will also increase the challenges you face, such as reducing the base time you have to complete it. The difficulty of these challenges scales with the quality of the Tribute and the current difficulty level of your world.

Higher-quality Tributes grant unique bonuses, such as Increased Experience Gain or awarding Runes upon completion. To claim these bonus rewards, you must reach at least Rank 1 Attunement, with successive ranks boosting the rewards even further.

Bargains are modifiers applied to Tributes at the Spirit Brazier. After placing a Tribute, you can select a Bargain to customize your run's rewards, such as increasing the chances of obtaining items with specific affixes or guaranteeing certain types of drops. Activating a Bargain requires resources like crafting materials or gold, so choose based on your current goals and available materials.

Beating the Undercity

tick-tock

There are three Districts in the Undercity and within each of them, there are 3 levels plus 1 Boss level. You do not get to select which District you will get when you activate the Undercity portal, it's randomly assigned.

• Cave District - Longtooth, The Wretched (boss)
• Temple District - Yoche, The Golden (boss)
• Ziggarut District - Alia, Kurast's End (boss)

Depending on which Tribute, if any, you offered at the Spirit Brazier you will begin with a set amount of time on a Timer that sits next to the minimap (see annotated image below). If this timer runs out before you make it through all three levels you will fail the dungeon. However, you can add seconds to the timer by destroying Afflicted monsters and objects.

There are different levels of afflicted monsters and the tougher the monster the more seconds their death adds to the timer. The more seconds you add the longer you have to build your Attunement Rank to 4.

• Minor Afflicted - 1 Second
• Lesser Afflicted - 10 Seconds
• Lesser Afflicted (named) - 15 Seconds
• Afflicted Object - 15 Seconds
• Greater Afflicted - 30 Seconds
• Mini-Boss Afflicted - 30 Seconds

Greater Afflicted

Afflicted Heathen's Wheel (object)

When you arrive at levels 1 to 3 you will be within a magic bubble that prevents the timer from ticking down. As soon as anyone in your party steps out of it the timer begins.

This gives you time to assess the map and most efficient route.

Inside the start bubble, time stands still

Plan an efficient route

Attunement Ranking

The end goal is to build your Attunement Rank up to level 4 (see image above) and make it through the portal to the boss level before the timer runs out. Once you reach the boss level the timer disappears. The higher your Attunement Rank the better and more plentiful your rewards will be when you kill the final District Boss. You must get to at least Attunement Rank 1 to receive any loot.

Undercity. What's what

You increase your Attunement by killing monsters and igniting multiple Beacons positioned across each level that add even greater boosts to your Attunement Rank.

Beacon done

It is not just a matter of tapping the Beacon to ignite it, you need to kill all the accompanying monsters to get the boost to Attunement. You will know when you've done that when the Beacon goes grey on your minimap. You'll also hear a speed boost ignite on you which you can use to speed to your next target.

Each of the three levels has Beacons to ignite but at the end of level 2 there will be a Grand Spirit Beacon with considerably more monsters surrounding it and clearing them all will add a lot of Attunement.

You'll see small Attunement flames appear where you are fighting and these represent the Attunement you have just earned but you do not need to collect them, they are just a visual aid.

Grand Spirit Beacon Event for Attunement

Once you reach Attunement Rank 4 you can head straight to the final portal to the Boss Level as there is no benefit to killing any more monsters. If you have reached a lower Attunement Rank but your timer is running out, leg it to the final portal and the boss. It's better to get some loot than just fail the dungeon run. Better luck next time.

Portal Pranksters

Portal Pranksters, unique to the Kurast Undercity dungeon, but do not appear every time. As with regular Treasure Goblins they only appear on the minimap when you are close and will try to escape through their portal. If you kill them you'll be rewarded with a bonus chest when you complete the dungeon.

Tips to Help You

• Speed is of the essence so ensure you have Boots with Movement Speed and get yourself an Elixir of Tailwind and Incense of Rushing Wind from Zyanya, the Dark Citadel Vendor in the Ancient Nexus (Map) which both boost speed by 15% for 30 minutes and 20 minutes respectively.
• Apply Movement Tempering affixes to your Boots and Amulet.
• Mobility skills such as the Sorcerer's Teleport and even Evade are very useful to get away from unnecessary fights so look for extra Evade charges on Boots.
• When you arrive on the level don't step out of the bubble before you've checked the map to plan your efficient route to the exit portal.
• Be sure to clear all monsters around the lit Beacons as when you do all party members get a sizeable speed boost as well as a Cooldown and Resource Cost Reduction.
• When you hit the Attunement Rank of IV, you're done and can head to the portal ignoring all monsters.
• Don't bother with unnecessary fights. There are enough Attunement points to claim by tapping and clearing Beacons and taking out Afflicted mobs only. They add time AND Attunement points.
• Focus on skills and equipment that inflict an area of effect and if possible anything that Pulls In the crowd to concentrate as many monsters in one tight spot that you can all offload onto.
